Summary
Endoscope ICG-integrated technology (eICG) enhances visualization during intracranial aneurysm surgery, offering improved views of critical structures compared to traditional microscopic ICG videoangiography (mICG-VA). This novel approach aids in confirming vessel patency in previously hidden areas.
Area of Science:
- Neurosurgery
- Medical Imaging
- Vascular Surgery
Background:
- Microscopic indocyanine green videoangiography (mICG-VA) is standard for intracranial aneurysm surgery, but has limitations in visualizing deep or obscured regions.
- Neurosurgical endoscopes offer wider visualization but lack integrated imaging capabilities.
Observation:
- A novel endoscope ICG-integrated technology (eICG) was applied during anterior communicating artery aneurysm clipping.
- This technique provided real-time imaging data during the surgical procedure.
Findings:
- eICG-VA offered enhanced visualization of the aneurysm sac/neck, parent vessels, branching arteries, and perforating arteries, especially in regions hidden from the microscope.
- The technology provided additional information on aneurysm occlusion and vessel patency compared to mICG-VA.
- eICG-VA allowed for magnified views and access to less accessible regions posterior to the aneurysm clip.
Implications:
- eICG-VA technology has the potential to improve surgical outcomes by providing comprehensive visualization of critical neurovascular structures.
- Combining eICG-VA with mICG-VA can enhance the confirmation of vessel patency in challenging surgical scenarios.
- Further development, including angled endoscopes and specialized filters, could further optimize visualization capabilities.
